I had finished a course of 6 IPL treatments for facial hair removal as well. To start with, tbh I didnt have thick hair, but I presumed the treatment would rid me of the facial hair i did have.
I finished my treatment a few weeks ago and i have noticed an improvement, but their are still a couple of light patches where their is hair and (cos i was shaving throughout) a couple of the hairs are long. Tempted as I am, I have left them, and am still considering whether to have more treatments using Cynosure laser, as the IPL treatment (which is what I had) isnt actually a proper laser treatment.
